Dark energy is a mysterious force that speeds up the expansion of the Universe.

Understanding the distribution of this force revealed that the likely fate of the Universe was to keep on expanding.

It will eventually become a cold, dead wasteland, researchers say.

Knowing the distribution of dark energy tells astronomers that the Universe will continue to get bigger indefinitely.

Eventually it will become a cold, dead wasteland with a temperature approaching what scientists term "absolute zero".

Professor Priyamvada Natarajan of Yale University, a leading cosmologist and co-author of this study, said that the findings finally proved "exactly what the fate of the Universe will be".

A little too convenient. On the other hand, its the only universe of the three types that has 0 energy

so what came before the big bang?

Asked in October 2005 on the British daytime chat show Richard & Judy, to explain his assertion that the question "What came before the Big Bang?" was meaningless, he compared it to asking "What lies north of the North Pole?"

Energy cannot be created or destroyed, us our own universe defying this law? Or is the energy being lost going somewhere

we really don't know much about a lot of things. so, just calm down.

How do you know the Universe isn't growing? You fuckers know nothing of the Universe, stop pretending like you do.

But that's bull! It's like religion, "Don't question it, it just is! God didn't come from anything or need a creator, he just is!" At the very least say "the universe expands and contracts, going through big bangs and crunches endlessly!"

The Universe could Vibrate? We're just seeing the outward expansion at the moment. There are endless possibilities. We have such a small perceptive of the universe, we'll never know.

When matter is converted into energy in our universe, as far as we know, it's impossible to convert that energy back into matter. This is related to the phenomena we know as entropy; that is, the universe always tends towards disorder. When you drive your car, the gas that combusts in your engine loses around half of that energy to heat, the tires lose lots of energy through friction and heat, etc. These phenomena basically describe the second law of thermodynamics. In a sense, yes the energy is sort of "going somewhere else" in the universe, where it's not retrievable. The total energy of the universe remains constant but the total matter, in a sense, does not.
